Chrome Buttons
According to the Google website – “Icons should generally be in PNG format, because PNG has the best
support for transparency. They can, however, be in any format supported by WebKit, including BMP, GIF, ICO,
and JPEG.” (https://developer.chrome.com/apps/manifest/icons)
“You may provide icons of any other size you wish, and Chrome will attempt to use the best size where
appropriate. For example, Windows often requires 32-pixel icons, and if the app includes a 32-pixel icon,
Chrome will choose that instead of shrinking a 48-pixel icon down. However, you should ensure that all of your
icons are square, or unexpected behavior may result.”
The following Icon sizes are recommended:
- 16x16 – extension’s favicon
- 19x19 – default Toolbar Button Icon size.
- 32x32 – for Windows purposes. If a shortcut is added to the desktop for a webpage, then the 32x32
size will be used. If not available, Chrome will reformat another icon size to 32x32.
- 38x38 – large default toolbar button icon
- 48x48 – used by the Extensions Management Page (chrome://extensions), to display logo next to the
Extension Name.
- 64x64 – optional
- 128x128 – used by the Chrome Browser Installation and Removal prompts, and the Chrome Web
Store.

Safari Buttons
.png format
- 16x16 – for toolbar button. Most of the icon will be transparent. The pixels for the center part of the
logo that should be displayed, can be drawn with either 256 or 16 colors.
- 24x24 – for toolbar button, if a large font size is being used. Same characteristics as 16x16.
- 32x32 – for the Extensions panel. Since colors can be used for this graphic, there is no need for
transparency. 256 colors work well.
